This enum specifies constants used to identify the format of the character sequence, with the meanings listed in Table 122.
|native_format||The native pathname format.|
|generic_format||The generic pathname format.|
|auto_format||The interpretation of the format of the character sequence is implementation-defined. The implementation may inspect the content of the character sequence to determine the format. [ Note: For POSIX-based systems, native and generic formats are equivalent and the character sequence should always be interpreted in the same way. — end note ]|
